I' m not sure about 3d shoots cause I haven' t done any. Low light hunting....Impact Cosmic. I looked for a " secret Battery" when I first saw it. Easily the brightest pin out there. I actually have it on my Mighty Mite and shoot the indoor spots with it. It' s not the best choice for the application, but I only care about having a " pair of slippers" comfortable hunting rig. It' s almost too bright for indoor shoots, but can' t be beat outdoors. I belive they have a 3 Pin setup now too.
